Tollwhomitmay concern: Be it known that I, 'Fmnx R. PRO- oomnn, s citizen of thevUn'ited States re-` 4may be turned from one position to another to project a pair of locking elements between theiron't wheels to prevent their being turned for steering purposes. In certom respects this invention discloses parte that are similar to those described in m Patnt No. 1,245,124, granted October 3 191 An exem' liicationA of' this invention in its preferre form is illustrated inthe accompanying drawing 'in the manner following:

Fi re 1 is va. front elevation of an automobi e'equippcd with myvimproved bumper Fig. 2 1s a lplan viewof the iront part et an automobileA showingthejbumper inplace;

Fig. 3 is an' enlarged transverse section taken fon linie 3 -3 of Aig. 2;- I

Fig. 4 is s `detail in transverse section faken on line 4-4 @i Fig.- mand Fi 5 and Gsretwo views in perspective showing the two brackets that connect the bumper to the automobile frame.

The arts of an automobile thntnre represented m the drawings include the two front wheels 10, each arranged to steer by swiveling around a pin 11 suitabl mounted on the front axle 12 that is carrie by the twoslde frames 13. For urposes of strength those frames are nella 1y of channel formation with upper and lower flanges i4, the forward end ofA euch A:frame being curved slightly down and havin at its extremity a web from which laterally a. boss 15 `formed with un opening therethrough `for receivin a. bolt lthat connects with' a. spring l'l'. t", l is common to most automobiles and has been alluded to only because the present bumper ed to cooperate in a special manner wit such parts. A

Referring now to Figs. 5 and 6, I have e' construction just,described illustrated two brackets that connect the bumper to the automobile, one bracket being attached to euch frame. These two brackets are substantially alike, and in the drawing their both sides `are accordingly shown. In form cach bracket comprises a bod 21 from which extends forwardly a ne 22-below which is also a shoulder 23 that is suitably 'shaped to abut one of the frame bosses l5 so as to derive su port therefrom. The bracket may bc renfgrced by providing nuirgnal flanges 24 as shown, which near the front end are shaped in the form of a cylindrical bearing 25 forward of which is a head 26 provided with upper undV lower cars 27 presenting in effect a channel formation. At the rear Aend of the bracket, upon that side of its body which is opposite .to 'the flanges 24,a11e two or more laterallyr extending channeled Vlugs 28 in registerV with openings 29 .formed through the bracket bod. f Y n In Figs. 3 an 4 the manner of attaching a bracket so'l formed to one of the channeled frames of the automobile' is clearly reprosented. For securingthe bracket 1n place, I use two or more hook bolts 30, one ar ranged throuvh cach o enng 29, Awith its shrink disposed within t 1e associated lug 2S,

lthe hook ond of each bolt catching on to the lower liu-ngel lfi. -By tightcninga. nut 31 bupon thogopposite end of the bolt against the proximate fac-enf the frame the bracket is bold rigidly in place. The advhnta o of this construction resides in the Simp icty nndeasc with whichV the bracket may be attached yor taken od', and in the secursfnsteningtlmtresults from the olampngoi two or more hook bolts upon the frame flange,` resting the shoulder 23 on 'the boss 15, and the. underla )ping of the framcby the lugs 28. It is p ein that the bolts serve principally to hold tho bracket in properA rela tion to the frame such that su vport for the bracket is derived almost entire y from other sources. j

The bumper proper is duplex in char'ncter, one part being arranged aheadof the other,` the numerals mand beilg'used todos-` ignntc these two arts respectively (see'Fig. 2). The forwarf bumper is preferably resilient und may consist of two spring bars :t4 and 35 averla )ping in the region of the front center an provided wit suitable proper key.

clamps 36 for maintaing them in e fixed adjustment relative to each other. Each bar is suitably turned back on itself as at 37 to present its end between the cars 2T of the head 26 of one of the brackets 20, any nppropriate means being employed for looking the )ar ends in place upon the bracket heads. The bumper 32 just described is fixedly held in position just forward of the second bumper element 2liwhich muy be in the form of a pipe or rod mounted to turn about a horizontal axis. For this purpose the bur 33 is journaled within the two bearingis- 25, one provided in cach bracket 20, in which endwise movements may be prevented as b the use of collars 38, as shown. Upon eaci end of the bar 33 I have Secured a sleeve 39 from which projects laterally an arm 40 that may Swing in a plane just inwardly of theI proximate wheel 10, the effect boing, when swung rcarwnrdly (as shown by the dotted lines in Fig. 3) to interfere with steering movements ol' thrtwo Forward wheels: of the vehicle.

Referring non' to Fig. 5i, upon one of the collars 3S is: carried a laterally projecting segmental plate 41 notched in two places as at 42 and 43, and provided with two stop shoulders 44 and 45. The curved edge of this plate is received within one side of a housing 45 that may be formed integral with one of the brackets 20, the plate being in juxtaposition to its neck 22. Arranged within the housin 46 is a. spring actuated locking bolt 47 ac apted to enter into the .lower notch 43 when the bumper bar is turned to u position where the two arms 40 interfere with steering movements of the wheels` l0. F or preventing normal retraction ol' the bolt n suitnblc lock 4S may be provided, adapted to be operated only by use of a Means are also provided for holding the bumper bar in no1-mel operating position with the two arms 40 free of the front wheels, and for this purpose, I have shown a second sn'ing actuated bolt 49 adapted to cuter the upper notch 42 only when the parts are related as shown by full lines in Fw. 3, a trigger 50 being provided for manually withdrawing this bolt 49 when it is desired to lock the vehicle. The two stops 44 and 45 copernte with the upper and lower sides of the housing, for the purpose of confining within pro er limits the swinging,r movements of the umper bar, which are facilitated by grasping u handle 51 arranged :is shown.

The construction that has been described represents a preferred embodiment of my invention. Changes or modifications from the exact form shown may, of course, be made, but in so far 'as such modifications follow the spirit of my invention as defined by the appended claims, I desire that they should be included within the scope of this patent.
